摘要
以套管式换热器作为热回收元件对循环加热式空气源热泵热水器的运行性能进行试验研究,指出:水箱水温从15℃升高到55℃时,系统参数如吸、排气压力,进、出水温度等随着水箱水温的变化而升高,同时系统的能耗也增大,而系统性能系数有所降低,在3.69左右,但与传统热水器相比系统还是节能的,是可行的.
Using coaxial pipe heat exchanger as heat recovery components, the operating performance on air source heat pump water heater with cylic heating was studied. Based on the experiment results, with wa- ter tank temperature ranging from 15℃ to 55℃ ,the system parameters such as inlet, exhaust pressure, inlet and outlet water temperature rose, the coefficient of performance was about 3.69 and showed the feasibility of this system.
